[patch snipped]

Jesper, I applied your patch to gnus-sum.el. I use Oort 0.06 btw. In
.gnus I set gnus-summary-thread-gathering-function to
gnus-gather-threads-by-reference. 

Now when I enter gnus.ding on quimby and look at articles
<Pine.LNX.4.44.0205151452570.4915-100000@yxa.extundo.com> and
<uk7q53f3s.fsf@axis.com>, they show up in my summary buffer like this:

!  [  31: Niklas Morberg         ] Gathering very loose threads
!  [  40: Simon Josefsson        ] Re: Gathering very loose threads

while the second one has In-Reply-To: <uk7q53f3s.fsf@axis.com>. Does
this mean I didn't apply you patch correctly or is my understanding of
thread gathering incorrect?

Regards,
Tom
